Specification of Letters Patent.

Application filed February 19, 1918. Serial No. 218,143.

GARRETT and JOSEPH OWEN S'IAUDE, citizens of the United States, residingat Fort Worth and Weatherford, respectively, in the counties of Tarrantand Parker, respectively, and State of Texas, have invented certain newand useful Improvements in Derailing- Blocks, of which the following isa specification.

Our invention relates to new and useful improvements in derailing blockssuch as are usedby railroads, and it has particular reference to adevice of this character which can be easilyand quickly clamped orfastened to one of the rails 'on a railroad track, our principal objectbeing to provide a derailing block which is portable, of comparativelylight weight and can be readily locked toA or removed from a rail asoccasion demands. I

In the carrying out of our invention we provide a block adapted to lieflat on the head of the rail, the top of the block being arched to raisethe Wheel of a car from the rail and having a flange for diverting thewheel from the railroad track as it takes the arch. The block proper isclamped to the web of the rail beneath the head by a canishaped leverarm arranged so that a Inovenient of the arm horizontally in eitherdirection is sufficient to fasten the block to or remove same from therail.

Our invention will be more fully and clearly understood by reference tothe accompanying drawing and the following description taken therewith:

Figure 1 is a side elevational view 0f a derailing block, embodying ourinvention arranged on the rail.

Fig. 2 is a top or plan view of the same.

Fig. 3 is a side elevational view taken from the side opposite to thatshown in Fig. l.

F ig. 4 is a cross-sectional View, taken on the line 5-5, of Fig. 2, and

Fig. 5 is a top viev of the cam-shaped lever arm for clamping the blockto the Referring to' the drawings, l represents the right hand rail of arailroad or railway t ek lo and on which the derailing block embodyingour invention is to be attached. This'v (len-.lling block has a body 2extending some distance beyond the inside edge of the rail 1 and to itsunder surface is pivoted a cam lever 3. The body 2 rests upon the headof rail l and extends upward therefrom in the form of a flange 4, theinner face of which is preferably straight and extends at an angle tothe rail from a point Patented Oct. il, tllle.

beyond the inner side of said rail to a point directly above the outerside of the head of said rail. The block 2 has a downwardly projectinglug or bearing 5 extending adjacent to the inner side of the head of therail and forming the pivotal support for cani lever 3, the cam of saidlever being held to the under face of said bearing by a screw bolt 6traversing an opening 7 arranged eccentrically of the cam of the leverand screwing into said lug 5. The bearing edge of the cam lever 3 isridged or corrugated as at 8 to more tightly grip the web of the railwhen the block is locked to positiOn. The upper surface of the camportion of the lever 3 is also provided with a wedge-shaped projection 9fitting under the head of the rail l to clamp the block down upon saidrail head when said cam lever 3 is moved horizontally to bite into theweb of the rail.

The outer side of block 2 is provided with one or more downwardlyextending hookshaped projections 10 which tit around and under the headof the rail to lock the block to the rail.

The upper face of the block 2 has on its outer side a rounded or archedprojection or cheek 11 resting on the top of the rail head. This cheekll receives theI rim of the wheel and guides said rim across the rail inthe derailingl operation. The Harige of the wheel is deflected into thechannel 12 of the block 2 between the flange L and cheek ll and saidflange 4 forms the bearing against which the flange of the wheel rides4as said Hange travels over the channel 12 of the block.

If desired the block r2 may be provided with a handle 13 whereby it maywhen released from the rail be carried to a new point of use ortransported by a brakeman to the train. --The block is of peculiarusefulness in prevent-ing rear end collisions in that it adds to theusual safeguard of a lnakcrnan and his flag an additional safeguard inthat if the approaching train Jfails to stop on the brakemans signal theblock in position will derail the oncoming train.

Having described Jthe nature and objects wardly projecting flangeextending in a `relatively straight line at a more or lessI of ourinvention, what we claim as new and desire to secure by Letters Patent,iS

1. In a derailing block, a body having its upper face contoured toreceive and guide the rim and flange of a Wheel, a means for hookingsaid body to the head at one side of the rail, and a cam lever pivotallymounted on the block at the opposite side of the rail, said leverarranged to swing horizontally under the head of the rail to bite intothe web of the rail and to clamp the block down upon the head of therail.

2. in a device of the character described an arched block having anupwardly extending' flange, the inner face of the upacute angle to therail, and 'having downwardly extending hook-shaped projections curvedunder the head pari; of the rail in combination with a Cain-shaped leverarm' pivotally connected to the under portion of the block lno clamp thebloelgto the web of the rail, said lever arranged lo swing horizontallyunder Athe head of Said rail to clamp The block down upen the head ofthe rail.

In testimony whereof We have signed our names to this specification.
